Score soccer-player abs with Kelley O'Hara's core-strengthening move

We know what you've been doing, because it's what we've been doing too: totally bingeing on World Cup Soccer and #ibelieve'ing all over the place on behalf of the USA.

We popped in to a Manhattan soccer Mecca, Chelsea Piers and were lucky enough to catch up with U.S. Women's National Team soccer player and Olympic gold medalist Kelley O'Hara just before the men's U.S. v. Belgium kickoff.

And guess what? In the midst of a busy season (yes, the Women's National Team regular season continues during the World Cup...and they are totally crushing it as usual) the wingback and Under Armour brand ambassador is bingeing on her fill of FIFA action right along with us!

"I'm so excited for the guys because so many people doubted that they would even make it out of their group so it is a big accomplishment that they are into the knockout round," says the soccer star. "Now it is just they've got the World Cup jitters out hopefully. They know how to play and they acclimated to the environment and the atmosphere and the speed of play. They should go out there and have fun. Every 90 minutes or 100 minutes could be your last so they should just leave it all on the field."

Since there are few things more motivating than going on a month-long soccer bender, we bet you are like the rest of us and wondering what it takes to get one of a player's most prized possessions, other than the most MAJOR title ever of course. Yup, we're talking about winning abs.

One of Kelley's guaranteed moves is one we also love: the rotating side plank. If you're watching the game and need to work out some nerves, these'll do the trick. We guarantee it's a way to earning your stars, stripes, and strong abs forever!
